Voltage/Noise Filters?

[SabrToothSqrl]

I believe these are noise/alternator filters installed by Formula from the factory. They only have 2 wire hook ups. Positive off the alternator and ground.

Does anyone know anything about them? One on each engine. Can't tell if they do anything.

At idle I get 'noise' through the stereo that I can drown out at higher volumes. If I turn the radio OFF at idle, I get noise through it still.

If I turn the engines off, all noise goes away. I haven't tested if it's 1 engine or both. I guess I could start with that.

Should I replace these? Remove them? Anyone have a make/model of them?

thanks!

I am no expert but I believe there are better devices that can be added to the stereo in place of these Old Technology suppressors. Here is one I found but there are plenty more out there.

Agree noise suppressor, had one on my cruiser.
Won't hurt anything to remove it.

Thanks. I'll do some checking to see if it's a specific engine that causes the noise. I'm guessing it's port as I start that one first, and the noise usually starts right way. but won't hurt to verify before I do anything. I'll remove the wiring. see if anything changes, then pull the gizmo's. then reevaluate.
